56 NATIONAL FOREST MANUAL. 



data collected which have a bearing upon the case and upon the com- 

 putation of capacities should be collated in tabular form in the report. 

 This instruction should be rigidly adhered to, since it will be ex- 

 tremely important at the 10-year revision period to have in their 

 original form the exact and complete data upon which the original 

 calculations are based. If the chief engineer in reviewing the report 

 of the district engineer makes alterations or corrections, or reaches 

 different conclusions with respect to power capacity or otherwise, the 

 report of the district engineer should be corrected accordingly before 

 the case is submitted to the Forester ; but if the district engineer, upon 

 a reexamination of the case, disagrees with the changes made by the 

 chief engineer, he may so state in his report, giving the reasons 

 therefor, and he will not, to such extent, be considered responsible 

 for the report. 



Under Regulation ~Lr-1 the term " construction of the works " 

 excludes all such preliminary work as surveys, road and trail build- 

 ing, clearing of land, etc. It will therefore be necessary, in inserting 

 the lengths of periods in article 4 of the stipulation, to allow a time 

 before construction must begin reasonably sufficient for the comple- 

 tion of all necessary preliminary work. It will be advisable, in gen- 

 eral, to confer with the applicant before fixing the time limits, with 

 the view of agreeing upon such limits as will be satisfactory to the 

 applicant while at the same 'time properly protecting the public 

 interests. 



Articles 4 and 5 of the power stipulation have been drawn for the 

 purpose of allowing permittees to make progressive developments 

 of two or more power projects upon the same stream or watershed 

 if they so desire. Each division of the works as taken in these 

 clauses should in general constitute a complete operating unit or 

 power project. But where, for example, it may be the applicant's 

 intention to construct several storage reservoirs not directly con- 

 nected with the water conduits, each reservoir may be, and in general 

 should be, taken as a distinct divison of the works. Water conduits 

 and the diverting dams and power houses connected therewith should 

 never be separated. 



Particular care should be exercised in the determination of the 

 total capacity of the power site. All the available data should be 

 secured, and where storage is to be used some graphical method, as 

 that of Rippl or Hill, should be employed. (See Mead's Water 

 Power Engineering.) The district engineer should review carefully 

 the estimates presented by the applicant and compare the same with 

 his own independent estimates. 



From the fact that probably in many instances the data for the 

 original calculations will be meager, provision is made in Regulation 

 L-8 for a redetermination of the power capacity by 10-year intervals 

 to admit of utilizing more complete data and to allow for possible 

 change of conditions. 



Upon receiving the district engineer's report the district forester 

 will prepare five copies of the stipulation on Form 61 and five copies 

 of the permit on Form 62. If the application is approved by the dis- 

 trict engineer and the district forester, they will initial the file copies 

 of the stipulation and the permit. The district forester will send 

 the chief engineer a copy of the complete application, one copy of 

 the district engineer's report, the original maps and plans on tracing
